如何获取Express nodejs中的路径权限？

Question

我在express node.js中是全新的。我有一个文件夹结构，如：

/Express 
    --server.js 
    --index.html 
    --home.html 
     /css/ 
     /js/ 
     /images 
     /fonts 

在index.html我正在访问一些javascript (js folder)，images (images folder)，fonts (fonts folder)。我也链接home.html从index.html页面。我也需要直接阻止访问home.html。

我写了express-ws这样的server.js：

var express = require('express'); 
    var app = express(); 
    var expressWs = require('express-ws')(app); 
    var path = require('path'); 

    //accessing index.html 
    app.get('/', function(req, res){ 
    res.sendFile(path.join(__dirname+'/index.html')); 

    }); 

    //How can i acess all the files inside the JS , CSS , Image and Font folder here ??? 

    //Also How can i link home.html from Index.html File and block home.html accessing publicly 

    app.ws('/', function(ws, req) { 
     ws.on('message', function(msg) { 
     console.log(msg); 
     }); 
     console.log('socket', req.testing); 
    }); 

    app.listen(8888); 

我如何可以访问index.html与server.js的JS，CSS，图像和字体文件夹内的所有文件有什么建议？还将home.html从index.html链接到直接访问块。

Answer 1

你应该对静态内容创建一个单独的文件夹一样public或其他任何东西，然后使用express.static()提供静态内容后，以下。因此，这里将是你更新的目录结构

/Express 
    --server.js 
    --index.html 
    --home.html 
    --/public/ (directory) 
      --/css/ (directory) 
      --/js/ (directory) 
      --/images/ (directory) 
      --/fonts/ (directory) 

和更新的代码将

var express = require('express'); 
    var app = express(); 
    var expressWs = require('express-ws')(app); 
    var path = require('path'); 

    //for js, css, images and fonts 
    app.use(express.static(path.join(__dirname, 'public'))); 

    //accessing index.html 
    app.get('/', function(req, res){ 
    res.sendFile(path.join(__dirname, 'index.html')); 

    }); 

    app.ws('/', function(ws, req) { 
     ws.on('message', function(msg) { 
     console.log(msg); 
     }); 
     console.log('socket', req.testing); 
    }); 

    app.listen(8888);

附加要求路径

// serve index.css at localhost:3000/index.css 
app.use(express.static('css')); // looks in current directory for css folder 

// serve index.js at localhost:3000/static/index.js 
app.use('/static', express.static('js')); // looks in current directory for js folder and appends /static to URL 

app.use(express.static('fonts'));
